Newbies Investing Questions

[shanetavarus]

I have a quick question for someone who considers themselves experience in Pennyland. I recently just started to trade and started off rather hot, maybe with 80% returns during my first two weeks. Now it seems I am in a rut losing most of my gains and principle during the last two weeks. Is it important for me to be able to short penny stock or can I have success just on the upside. I am with a broker who does not offer shorts on pennies. Is this bad? Is it necessary for me to have success that I be allowed the option to short them? And last but not least, they are so dramatic in the volitility one day there up and I get in and the next day they are down BIG, WTF!!! I this due to short play? Please give some advice, I have been wraping my head around this all day.
